Internet Explorer 11 has been installed in the preview version release of Windows 8.1 which is for developer build.　In the Windows 10, we felt that the execution speed of response and animation to a CSS property is much higher mature. IE which is the next version further improve drawing speed. We are strongly expecting high degree of perfection of it because it put out a performance for more than Google Chrome in the benchmark test.
